NHS Supplier Invoice Finance
Businesses supplying NHS organisations may be able to fund eligible unpaid invoices for delivered goods or completed services. This can support ongoing trading and the next stock purchase. Purchase orders and stock that has not yet been delivered need a separate assessment.
- Eligible invoices after delivery or service completion.
- Concentrated NHS debtor books and restricted availability.
- A separate plan for stock before an invoice exists.
For suppliers seeking business funding. This is not an NHS procurement scheme or government-backed finance. NBS Finance is a commercial finance broker and introducer, not a lender.
Follow the order-to-payment chain
| Trading stage | Evidence and funding distinction |
|---|---|
| Order received | Check the contracting entity, valid purchase order, quantities, price and cancellation terms. An order is not an eligible completed invoice. |
| Stock purchased or manufactured | Supplier payments may precede delivery. Assess trade, stock or other working-capital finance separately. |
| Delivery or service completed | Keep delivery, receipt or acceptance evidence and resolve discrepancies. |
| Correct invoice submitted | Match the payer, PO, billing requirements and accepted value. Eligible unpaid debt may support invoice finance. |
| Payment received | Customer receipts repay the financed debt; residual proceeds depend on charges, reserves and other drawings. |
The exact debtor matters: a trust, an integrated care board, a purchasing organisation and a distributor are not interchangeable. Identify the legal entity that owes your business and whether contractual deductions, rebates or set-off may apply.
Why an NHS invoice may be held or returned
NHS SBS’s supplier guidance states standard payment terms of 30 days from receipt of a valid, undisputed invoice. Its good-invoicing guidance highlights correct organisation details and PO references; mismatches can prevent processing. These sources describe the organisations and arrangements they cover, not every NHS contract. NHS SBS supplier FAQs; good invoicing practice.
- Check the invoice went to the correct legal payer and submission channel.
- Match PO number, price, quantity and goods-receipt or service approval evidence.
- Establish whether the invoice is recorded, accepted, queried or awaiting authorisation.
- Reconcile short payments and credit notes; keep disputed amounts separate.
- Escalate overdue accepted invoices through the buyer’s published finance process.
A normal credit period creates a timing gap; an invoice past its due date is overdue. Do not assume public-sector customers always pay late, or that funding will cover rejected invoices. Patient data is not needed for an initial funding review.
What an invoice-finance provider will assess
- Eligible receivables for completed delivery or services, with an identifiable commercial debtor.
- Contract and invoice evidence, receipt/acceptance, disputes, credits and debt ageing.
- Debtor concentration and the aggregate exposure across related NHS customers.
- Assignment, notification, collection account and any restrictions or existing security.
- Trading performance, margin, stock cycle, management controls and realistic cash requirements.
There is no universal NHS advance rate. A concentration cap, credit limit, reserve, age exclusion or current drawing can reduce usable cash below the headline percentage. The lender’s facility ceiling is also a separate limit.
A concentrated NHS ledger: a verified third-party case
Ultimate Finance published a case on 22 September 2026 describing a £750,000 invoice finance facility for Forma-Care (UK) Ltd, an adult incontinence-product supplier. Its existing lender had reduced pre-payment availability after sales fell below forecast. Ultimate Finance reports structuring the replacement around an NHS-focused debtor book and managing the transfer. Read the original Ultimate Finance case.
This was Ultimate Finance’s transaction, not an NBS deal. It demonstrates that concentration can be assessed commercially in a particular case. It does not establish today’s lender appetite, approval for another supplier, membership of NBS’s panel, or the terms you would receive.
For your business, establish whether availability has fallen because the eligible ledger is smaller, a customer limit changed, invoices aged, reserves increased or another covenant was triggered. A larger advertised facility may not fix the underlying restriction.
Existing lender restrictions and switching providers
Prepare a current availability statement and compare it with the same-date ledger: eligible invoices, concentration limits, reserves, existing drawings and net cash available. Include notice, minimum-term and exit provisions, security and any guarantees. Review your existing invoice finance facility before deciding whether to stay, renegotiate or switch.
Where applicable, the UK Finance Inter-Member Transfer Protocol helps participating invoice-finance and asset-based-lending providers coordinate a transfer. It is not the current-account switching service and does not waive notice, settle disputes or guarantee the next facility. Agree settlement, assignment, customer payment instructions and any cash gap before ending the existing arrangement. UK Finance switching guidance.
Stock before billing: compare the right funding route
| Route | Possible purpose | Key limitation |
|---|---|---|
| Invoice finance | Cash against eligible unpaid completed invoices; proceeds may help replenish stock. | Does not automatically fund a future invoice or purchase order. |
| Trade or purchase-order finance | A separately assessed supplier-payment or confirmed-order requirement. | Order quality, supplier, delivery, margin and repayment mechanics must work; access is conditional. |
| Stock finance or asset-based lending | Funding assessed against eligible inventory, potentially alongside invoices. | Stock type, ownership, valuation, turnover, controls and existing security matter. |
| Business loan | A defined working-capital or investment need with sustainable repayment. | Repayments and total costs must remain affordable if trading slows. |
Explore trade finance, purchase-order finance or asset-based lending where stock precedes invoices. NBS assesses access through lenders and specialist partners; these are not automatic NHS funding entitlements.
Calculate the cash you can actually use
Hypothetical example: a £200,000 NHS ledger includes £20,000 queried invoices and £10,000 outside a proposed age limit. That leaves £170,000 for eligibility assessment before concentration limits or reserves. If the agreed advance were 80%, gross availability would be £136,000; deduct £100,000 already drawn and an assumed £6,000 reserve to leave £30,000 before applicable charges. All amounts, the age exclusion and the 80% rate are invented to illustrate the calculation, not an offer.
Ask for the service fee, funding or discount charge, minimum fees, audit and administration charges, legal costs, guarantees, notice period and exit costs. Compare usable cash after exclusions, reserves, debtor limits and existing drawings—not just the advertised advance percentage. Compare invoice finance costs.
Factoring can include collections support; invoice discounting generally leaves more ledger management with the business. Notification, confidentiality and payment routing depend on the agreed structure. Recourse can leave you responsible if the customer does not pay; any bad-debt protection has limits and exclusions. British Business Bank guidance explains the benefits and drawbacks.
Funding cannot repair a structurally loss-making supply contract. Compare net margin after freight, returns, rebates and finance costs, and stress-test slower sales and delayed receipts. No general setup or payment-speed promise applies.
Information for an NHS supplier funding review
- Business accounts, management information, turnover and cash-flow forecast.
- Aged debtor ledger naming the actual commercial payers and concentration shares.
- Sample redacted accepted invoices, PO and delivery/service evidence.
- Contract payment terms, rebates, set-off and assignment arrangements.
- Stock ownership, supplier terms and order cycle where pre-invoice finance is needed.
- Current provider statement, reserves, debtor limits, security and notice/exit terms.
For the initial enquiry, give business-level totals, trading history, approximate turnover, required amount and date, monthly invoice value, total unpaid invoices, largest commercial debtors, payment terms, disputes and existing facilities. “Not sure” is preferable to an invented figure.
Do not send identifiable care recipient, patient or child information, medical records, care histories or placement files. If commercial documents are needed later, agree a secure process and appropriate redaction first. Missing documents can be discussed; an enquiry does not guarantee finance.
Your questions, answered
Can a single NHS debtor qualify?
Potentially, but each provider assesses concentration, payer identity, contract and ledger risk. Public-sector status does not remove those checks.
Can a purchase order be financed as an invoice?
No. An order or unsigned contract is not a completed, accepted receivable. Pre-delivery needs require a separate funding route and assessment.
Will switching restore my previous availability?
There is no guarantee. Compare the new provider’s eligibility rules, limits, reserves, fees and transfer requirements on the same ledger.
